COIL AND COP-HOLDER FOR WIRE-NETTING MACHINES.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed July 6, 1905. Serial No. 268,463.

To all whom it may concern:

, Be it known that I, ARTHUR E. BARLOW, a citizen of the United States,residing at Vorcester, in the county of /Vorcester and State ofMassachusetts, have invented a new and useful Cop and Cop-Holder forVire- Netting Machines, of which the following is a speciiication.

This invention relates to that class of machines which are employed formaking chicken coop wire netting.

The especial object of this invention is to provide a strong, simple andefficient form of cop and cop-holder having means for locking the samein place against accidental displacement, and which are pivoted so thatthey can turn with comparatively little friction.

To these ends this invention consists of the cop and cop-holder and ofthe combinations of parts therewith as hereinafter described and moreparticularly pointed out in the v claims at the end of thisspecification.

In the accompanying drawing, Figure l is a transverse sectional view ofsumcient parts of a wire netting machine to illustrate the applicationof this invention thereto. Fig. 2 is an enlarged sectional view partlybroken away of sufficient parts of a machine to illustrate theapplication of a cop and cop-holder thereto. Fig. 3 is a side view 'ofthe cop partly broken away. Fig. 4 is a side view of the cop-holderpartly broken away. Fig. 5 is a fragmentary view similar to Fig. 2showing the locking catch unfastened so as to permit the cop andcop-holder to be inserted into or taken out of the machine, and Fig. 6is a detail view of a division piece for the cop showing a guide piecefor the wire.

. In machines which are used for making the so-callec chicken coopnetting, one half of the wires are taken from reels or other sources ofsupply, while alternate wires are furnished from cops or bobbins. Thecopholders are mounted in bearings in top and bottom twisting gears. Thetop and bottom twisting gears are made in half sections and are shiftedtransversely between the making of successive twists, so that a wirefrom any one cop is twisted alternately with the reel wires at the sidesthereof. In this class of machines the cops and cop-holders are theparts which give the most trouble. In most of the machines thecop-holders are simply dropped into place in bearings in the twistinggears, and it sometimes happens that a number of such cop-holders willbecome displaced from their bearings and will drop out of position inthe machine, requiring the stopping of the machine and the replacementof the parts. In these machines, also the cops and cop-holders must bemounted so that they will turn readily upon their bearings, permittingwires to be supplied as fast as required without breaking or kinking.

In a wire netting machine equip ed according to this invention each of te copholders is held in place in its bearings by means of a simple andefficient locking device which will prevent the cop-holder from beingaccidentally displaced, while permitting it to be readily unlocked andtaken out whenever the cop or bobbin thereof requires refilling. The copand cop-holder are supported upon a step bearing which is preferablyprovided with a bearing ball in an oil socket which contains suflicientoil to keep the bearing well lubricated.

Referring to the accompanying drawing for a detail description of a copand copholder constructed according to this invention, and of sufficientparts of a wire netting machine to illustrate the application of thisinvention thereto, as shown in Fig. l, A designates one of the endframes of a wire netting machine. Mounted upon and supported by theframes A are fixed top and bottom gear rails R and R. Coperating withthe fixed gear rails are movable gear rails M and M. Mounted in therails R and M are the top split twisting gears, one-half of each ofwhich receives one of the reel wires, and the other half of each ofwhich is provided with a downwardly extending bearing S for engaging thetop of a cop-holder. Mounted in the rails R and M are the bottom splittwisting gears one-half of each of which receives one of the reel wiresW, and the other half of each of which is provided with an upwardlyextending step Sfor supporting the cop and its holder. The netting asfast as made is fed out by a feed roll F, and may be rolled up ordelivered in any of the usual ways. The parts as thus referred to may beof any ordinary or usual construction and need not be herein describedat length.

The cop and its holder which I have devised is most clearly illustratedin Figs. 2 to 6 inclusive. As shown in these figures, the cop-holderconsists of a tube 10 having an upper slot 11 and a lower slot 12. Theseslots are provided for the purpose of permitting the operator to seewhere the wire is, and Vfor convenience in threading the wire intoplace. Mounted in the tube 10 and pinned rigidly in place therein is adivision piece 13. Mounted in a socket in the piece 13 is a springnpressed pin 14 which is held in place by a cover-plate 15. Pivoted onthe covenplate 15 is a bell-crank locking lever 16, one leg of which isengaged by the spring-pressed pin 14. At its upper end the tube 10 cithe copholder iits onto the bearing S. The copor bobbin as hereinillustrated, comprises a tube or bobbin 17 having a headlS at its upperend. The bobbin head 18 is provided with a pivot pin or pintle 19engaging the center hole of the division piece 13. Fastened in the lowerend oi the pipe 17 is a step 2O which is provided with a counter-sunksocket for resting on a bearingeball 21 mounted in an oil well in thestep S. The wire W which is wound on the bobbin extends out through theslot 11 as shown in Fig. 1, and in passing the collar or piece 13 thewire N preferably runs in a guide piece 22 illustrated in Figs. 4 and 6.It is shown extending out through the slot 11 for convenience only, asin prac tice the wire does not project through the slot in this way.rlChe guide piece 22 consists of a small trough-shaped piece of hardenedsteel which may be vfastened in place by one or more screws 23. rllheguide piece 22 is preferably highly tempered, so that it will not beworn or cut by the wire which is drawn up through the same.

1n the operation of a netting machine equipped according to thisinvention, whenever it is desired to remove a cop and its holder, thelocking lever 16 may be released by inserting a rod through the upperpart of the slot 11, and when the locking lever is released the cop andthe cop-holding tube may be lifted as shown in Fig. 5, so that saidparts may be taken out lfrom the machine, land if desired a newcop-holder inserted.

l/Vhen the parts are in normal position, as illustrated in Fig. 2, the-cop and cop-holder will be securely locked in place so that they cannotbe `accidentally displaced, while the weight of each cop and itscop-holder rests upon a thoroughly lubricated bearing ballso that thesame can be readily turned without breaking or kinking the wire.

l am aware that various changes may be made in the construction of mycop and copholder in applying them to diil'erent makes and arrangementsof wire netting machines.

1 do not wish, therefore, to be limited to the 'construction 1 yhaveherein shown and described, but

Vhat l do claim and desire to secure by Letters-Patent of the UnitedStates is 1. 1n a wire netting machine, the combination of a cop, a copholder, and a locking device for the holder comprising a bell-crankmounted in the upper part of the holder and adapted to engage a bearingextending down from an upper twisting gear` to lock the holder against arising motion in the bearings.
